Polyolefin material as well as preparation method and application thereof

Abstract

The invention discloses a polyolefin material as well as a preparation method and application thereof. The polyolefin material comprises the following components: 15-95 parts of polyolefin resin, 5-60parts of reinforcing fibers, 0.5-10 part of a compatilizer, and 5-60 parts of hollow mullite microspheres. By adding the reinforcing fibers and the hollow mullite microspheres into the polyolefin material, the reinforcing fibers and the hollow mullite microspheres have a synergistic effect, so that the density of the material can be remarkably reduced, the wave-transparent performance of the material can be improved, the strength and heat resistance of the material can be improved, and the prepared polyolefin material has the advantages of high heat resistance, high strength, low density andhigh wave transparency.

Description

technical field

[0001] The invention belongs to the field of polymer materials, and in particular relates to a polyolefin material and its preparation method and application. Background technique

[0002] Polyolefin materials are the most widely used in real life due to the characteristics of abundant raw materials, low price, easy processing and molding, and excellent comprehensive performance.

[0003] At present, the reinforcement method of conventional polyolefin mainly uses glass fiber as a reinforcing medium, and utilizes the high strength and high rigidity of glass fiber to improve product strength and heat resistance. However, with this method, the glass fiber reinforced polyolefin after adding glass fiber has defects such as high density, poor wave transmission performance (large dielectric constant and dielectric loss), poor toughness, etc., which cannot meet the requirements of weight or wave transmission performance. Use on high occasions. In order to improve t...
